Application July 2, 1956, Serial No. 595,304

6 Claims. (Cl. 20-52) This invention relates to an improved adjustable vertical sliding sash, and has for one of its principal objects the provision of a sliding sash for doors or windows which embodies a novel locking means, whereby the sash will be automatically maintained in any desired position at the will of the operator.

One of the important objects of this invention is to provide a sash which is vertically slidable and which will work equally well as a screen or window, and which is provided with a simple combination release and operating handle or the like, whereby the same can be conveniently moved up and down, and whereby it will automatically assume a desired position and will be retained in that position until a further operation.

Another important object of this invention is to provide in a sash construction a simple yet eflicient locking cam which will act as a positive lock when desired and which will also act as a friction brake when the sash is moved in one direction or another, if such a braking action is desired and depending upon the type of sash.

A still further important object of the invention is to provide a combination lock and braking cam for a slidable sash wherein the braking action can be changed and regulated at the will of the operator.

Other and further important objects of the invention will be apparent from the disclosures in the accompanying drawings and following specification.

The invention, in a preferred form, is illustrated in the drawings and hereinafter more fully described.

The reference numeral 12 indicates generally a door into which the improved vertical sliding sash of this invention is incorporated. Obviously this may be a window or similar construction and wherever a sliding sash is employed.

As shown, there are usually two of the sliding sashes l4 and E6, and a screen or the like 18 may be fitted into the opening in the door or window, if such is desired. A frame 20, preferably of suitable metal or other material, is built into the opening in the door or window. This frame may be of extruded metal and is usually in four sections, fitted into the sides, top and bottom of the opening, in any suitable manner, and the extrusion can be of the shape as best shown at 22 in Figure 4. Obviously other types of holder, frame or track can be employed.

The sash elements may also be of extruded metal and in cross section can be of the shape shown at 24 in Figures 4, 5, 7, 8 and 11. Here again other shapes and contours may be employed.

The glass panes 26 are fitted into the sash elements 24 in any suitable manner and putty or other sealing element 28 is ordinarily employed.

The glass holding sashes are vertically slidably fitted into the frame elements 22 and the adjustable combination locking and frictional brake means of this invention is then installed in the top element of each sash 14 and 16.

This comprises essentially a bar 38 which is preferably 7 or" the extruded frame element 22, while the cam bar 30 of the inside sash is inside of the corresponding juxtaposed part of the extruded frame member 22 but that both of the cam bars will, when tilted from a normal vertical position, rub against the adjacent frame part.

This tilting is accomplished by means of a thumb latch or handle 32, which is fitted onto the cam bar 30 in any suitable manner, as shown in Figures 7, 8, and 9. That portion of the thumb latch or handle 32, which fits around the cam bar St is fitted into the channeled portion of the sash element 24 and protrudes through an opening 34, which is made in the sash for that purpose. A corresponding gripping or latch element is also fitted into the opening, the particular element being best shown in perspective in Figure 10 and includes a projection 36 and an interior integral base element 38, which is preferably provided with integral lugs or the like 40 by means of which the same can be fitted into the opening 34. The extending handle portion 32 of the cam latch element passes through an opening 44 in the cooperating gripping element as shown-in Figure 10. Each of the projections 32 and 34 is provided with a recess 48 and 54) respectively and a helical spring 52 is fitted into these recesses whereby the elements 32 and 36 will normally be held in spaced apart relationship, and such relationship will accordingly urge the cam bar Sit into tilted position as shown in Figure 7. This provides a normal locking relationship between the ends of the cam bar and the corresponding portions of the extruded frame element 22, and it will be noted that the action of the spring 52 is sufiicient in all cases to provide a wedging action whereby the sash 14 will be positively and firmly held in any set position after it has been moved to that position by the operator and when the movement is accompanied by a squeezing together of the thumb and finger latch elements 32 and 36 against the tension of the spring 52. As soon as the latch elements 32 nd. 3.6.,are. released,..the. cam b21113!) will. be. tilted from its.

The screen 18 is usually held in position by means of molding 5.61 -in.the, event that a. screenis :employed.

A .slight modification of the'invention is 'shown in Figureqll, wherein acam bar. 39:: isemployed, which acts in thersame manner as the cam bar 30. This has a thumb latch, or; handle, 6%, welded or otherwise .aflixedithereto -which cooperates with a. corresponding latch or grip-i pingIelementGZ fitted onto the. sash framefid: andheld in position by means of a rivet 54a. The elements 63 and 62.are provided with protuberances 64.11pm. which a helical spring 52a is positioned.

The elements 32, 363840..can be moldediof some suitable plastic or canbe die-cast of metal or otherwise I produced anda Weather strip '70 is ordinarily fitted into theouter edges of the sash frames 24-asbest shown in Figure 5.

Itwill be evident that herein is provided'a-vertical sliding sash having an improved locking and braking element whereby the same can be instantaneously placed in a desirediposition in theframe and automatically held in that position with little or no efiort on the part of the operator. Additionally, the movement'of the sash both upward and downward can be braked as desired during operation and in case of an inadvertent or accidental release of the latch elements the sash will not accidentally drop which might causedamage or injury.

I. am aware that many changes may be made and numerous details of construction varied throughout a wide range-without departing from the principles of this inven- 4.x 11011,..311CL1, thereforenn.notpropnselimiting he p tent granted hereon otherwise than as necessitated by the prior art.
